The body portion 3110 may be partially or entirely made of an aluminum-based material (e.g., a high-strength aluminum alloy or a composite aluminum alloy coated with a high-strength alloy), a magnesium-based material, a stainless steel-based material, a titanium-based material, a tungsten-based material, any combination thereof, and/or other suitable types of materials. Alternatively, the body portion 3110 may be partially or entirely made of non-metal material (e.g., composite, plastic, etc.). The golf club head 3100 may be a putter-type golf club head (e.g., a blade-type putter, a mid-mallet-type putter, a mallet-type putter, etc.). Based on the type of putter as mentioned above, the body portion 3110 may be at least 200 grams. For example, thebody portion 110 may be in a range between 300 to 600 grams. AlthoughFIGS. 30 and 31 may depict a particular type of club head, the apparatus, methods, and articles of manufacture described herein may be applicable to other types of club heads (e.g., a driver-type club head, a fairway wood-type club head, a hybrid-type club head, an iron-type golf club head, etc.). The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The body portion 3110 may include a
hosel portion 3145 configured to receive a shaft (not shown) with a grip (not shown) on one end and the golf club head 3100 on the opposite end of the shaft to form a golf club. The front andrear portions front portion 3150 may include a face portion 3155 (e.g., a strike face). Theface portion 3155 may be used to impact a golf ball (one shown as 500 inFIG. 5 ). Theface portion 3155 may be an integral portion of the body portion 3110. Alternatively, theface portion 3155 may be a separate piece or an insert coupled to the body portion 3110 via various manufacturing methods and/or processes (e.g., a bonding process, a welding process, a brazing process, a mechanical locking method, a mechanical fastening method, any combination thereof, or other suitable types of manufacturing methods and/or processes). Theface portion 3155 may be associated with a loft plane that defines the loft angle of the golf club head 3100. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The body portion 3110 may include one or more weight ports and one or more weight portions similar to any of the golf club heads described herein. For example, a
weight port 3120 is shown inFIG. 31 . For example, the body portion 3110 may include a first set of weight ports (not shown) similar to theweight ports 2320 of thegolf club head 1600 and a second set of weight ports (not shown) similar to theweight ports 2340 of thegolf club head 1600 that are configured to receive a plurality of weight portions. Accordingly, a detailed description of the weight ports and weight portions of the golf club 3100 is not described. Alternatively, the body portion 3110 may not include any weight ports and/or weight portions. - The body portion 3110 may be a hollow body including an
interior cavity 3182 extending between thefront portion 3150 and theback portion 3160. Further, theinterior cavity 3182 may extend between thetop portion 3170 and thesole portion 3180. Acavity wall portion 3184 may separate theinterior cavity 3182 and theface portion 3155. Theinterior cavity 3182 may be associated with a cavity height 3186 (HC), and the body portion 3110 may be associated with a body height 3188 (HB). While thecavity height 3186 and thebody height 3188 may vary between the toe and heel portions, thecavity height 3186 may be at least 50% of a body height 3188 (HC>0.5*HB). For example, thecavity height 3186 may vary between 70% and 85% of thebody height 3188. With thecavity height 3186 of theinterior cavity 3182 being greater than 50% of thebody height 3188, the golf club head 3100 may produce relatively more consistent feel, sound, and/or result when the golf club head 3100 strikes a golf ball via theface portion 3155 than a golf club head with a cavity height of less than 50% of the body height. However, thecavity height 3186 may be less than 50% of thebody height 3188. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In one example, the
interior cavity 3182 may be unfilled (i.e., empty space). Alternatively, theinterior cavity 3182 may be partially or entirely filled with a filler material (e.g., generally shown as 3190). Thefiller material 3190 may be an elastic polymer or elastomer material (e.g., a viscoelastic urethane polymer material such as Sorbothane® material manufactured by Sorbothane, Inc., Kent, Ohio), a thermoplastic elastomer material (TPE), a thermoplastic polyurethane material (TPU), and/or other suitable types of materials to absorb shock, isolate vibration, and/or dampen noise. For example, at least 50% of theinterior cavity 3182 may be filled with a TPE material to absorb shock, isolate vibration, and/or dampen noise when the golf club head 3100 strikes a golf ball via theface portion 3155. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In another example, the
filler material 3190 may be a polymer material such as an ethylene copolymer material to absorb shock, isolate vibration, and/or dampen noise when the golf club head 3100 strikes a golf ball via theface portion 3155. In particular, at least 50% of theinterior cavity 3182 may be filled with a high density ethylene copolymer ionomer, a fatty acid modified ethylene copolymer ionomer, a highly amorphous ethylene copolymer ionomer, an ionomer of ethylene acid acrylate terpolymer, an ethylene copolymer comprising a magnesium ionomer, an injection moldable ethylene copolymer that may be used in conventional injection molding equipment to create various shapes, an ethylene copolymer that can be used in conventional extrusion equipment to create various shapes, and/or an ethylene copolymer having high compression and low resilience similar to thermoset polybutadiene rubbers. For example, the ethylene copolymer may include any of the ethylene copolymers associated with DuPont™ High-Performance Resin (HPF) family of materials (e.g., DuPont™ HPF AD1172, DuPont™ HPF AD1035,DuPont® HPF 1000 and DuPont™ HPF 2000), which are manufactured by E.I. du Pont de Nemours and Company of Wilmington, Del. The DuPont™ HPF family of ethylene copolymers are injection moldable and may be used with conventional injection molding equipment and molds, provide low compression, and provide high resilience. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
filler material 3190 may be injected into theinterior cavity 3182 by an injection molding process via aport 3192 on the body portion 3110 as shown inFIG. 30 . Theport 3192 may have anopening 3194 on the body portion 3110 to allow injection of the filler material into theinterior cavity 3182 through theport 3192. Theport 3192 may have aplug 3196, by which theopening 3194 may be closed after injection of thefiller material 3190 into theinterior cavity 3182. Alternatively, as shown in the example ofFIG. 31 , at least one of theweight ports 3120 on the body portion 3110 may be connected to theinterior cavity 3182 through aconnection port 3122 that may be similar to theport 3192. Accordingly, the filer material may be injected into theinterior cavity 3182 from the at least oneweight port 3120 through theconnection port 3122. - For example, at least 50% of the
interior cavity 3182 may be filled with a TPE material to absorb shock, isolate vibration, dampen noise, and/or provide structural support when the golf club head 3100 strikes a golf ball via theface portion 3155. With the support of thecavity wall portion 3184 and filling at least a portion of theinterior cavity 3182 with an elastic polymer material, theface portion 3155 may be relatively thin without degrading the structural integrity, sound, and/or feel of the golf club head 3100. In one example, theface portion 3155 may have a thickness of less than or equal to 0.075 inch (e.g., the thickness of the cavity wall portion 3184). In another example, theface portion 3155 may have a thickness of less than or equal to 0.060 inch. In yet another example, theface portion 3155 may have a thickness of less than or equal to 0.050 inch. Further, theface portion 3155 may have a thickness of less than or equal to 0.030 inch. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. The apparatus, methods, and articles of manufacture described herein may be implemented in a variety of examples, and the foregoing description of some of these examples does not necessarily represent a complete description of all possible examples. Instead, the description of the drawings, and the drawings themselves, disclose at least one example, and may disclosure alternative examples. - In the example of
FIG. 31 , agolf club head 3200 may include abody portion 3210. Thebody portion 3210 may include atoe portion 3230, aheel portion 3240, afront portion 3250, arear portion 3260, atop portion 3270, and asole portion 3280. Thebody portion 3210 may be manufactured via various manufacturing methods and/or processes (e.g., a casting process, a forging process, a milling process, a cutting process, a grinding process, a welding process, a combination thereof, etc.). Thebody portion 3210 may be partially or entirely made of an aluminum-based material (e.g., a high-strength aluminum alloy or a composite aluminum alloy coated with a high-strength alloy), a magnesium-based material, a stainless steel-based material, a titanium-based material, a tungsten-based material, any combination thereof, and/or other suitable types of materials. Alternatively, thebody portion 3210 may be partially or entirely made of non-metal material (e.g., composite, plastic, etc.). Thegolf club head 3200 may be a putter-type golf club head (e.g., a blade-type putter, a mid-mallet-type putter, a mallet-type putter, etc.). Based on the type of putter as mentioned above, thebody portion 3210 may be at least 200 grams. For example, thebody portion 3210 may be in a range between 300 to 600 grams. AlthoughFIG. 31 may depict a particular type of club head, the apparatus, methods, and articles of manufacture described herein may be applicable to other types of club heads (e.g., a driver-type club head, a fairway wood-type club head, a hybrid-type club head, an iron-type golf club head, etc.). The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
body portion 3210 may include ahosel portion 3245 configured to receive a shaft (not shown) with a grip (not shown) on one end and thegolf club head 3200 on the opposite end of the shaft to form a golf club. The front andrear portions body portion 3210. Thefront portion 3250 may include a face portion 3255 (e.g., a strike face). Theface portion 3255 may be used to impact a golf ball (one shown as 500 inFIG. 5 ). Theface portion 3255 may be associated with a loft plane that defines the loft angle of thegolf club head 3200. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
body portion 3210 may include one or more weight ports and one or more weight portions similar to any of the golf club heads described herein. For example, thebody portion 3210 may include a first set ofweight ports 3320 on therear portion 3260. In the examples ofFIGS. 32-37 , therear portion 3260 includes aback wall portion 3262 having afirst weight port 3322 of the first set ofweight ports 3320 and asecond weight port 3324 of the first set ofweight ports 3320. Thefirst weight port 3322 may be closer to thetoe portion 3230 than thesecond weight port 3324. Thesecond weight port 3324 may be closer to theheel portion 3240 than thefirst weight port 3322. The first andsecond weight ports back wall portion 3262 or therear portion 3260. Thebody portion 3210 may not include any weight ports on theback wall portion 3262. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In the example of
FIGS. 32-37 , thebody portion 3210 may include a second set ofweight ports 3340 as shown inFIG. 35 proximate to theheel portion 3240 and extending between thetoe portion 3230 and theheel portion 3240. The second set ofweight ports 3340 may include any number of weight ports, such as three weight port as shown inFIG. 34 asweight ports body portion 3210 may include a third set ofweight ports 3360 that may be located near the toe portion and extend between thetoe portion 3230 and theheel portion 3240. The third set ofweight ports 3360 may include any number of weight ports, such as three weight port similar to the weight ports of the second set ofweight ports 3340. The second and third sets ofweight ports body portion 3210. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
golf club head 3200 may include a plurality of weight portions. Each weight port may be configured to receive a weight portion. For example, theweight ports weight ports 3320 may receiveweight portions weight ports weight ports 3340 may receiveweight portions weight ports 3360 may receive weight portions similar to the second set ofweight ports 3340. In the example ofFIG. 37 , theweight port 3362 of the third set ofweight ports 3360 is shown to have received a weight portion 3372. The configurations of the weight ports and the weight portions (e.g., inner diameter, outer diameter, size, shape, distance from an adjacent weight port or weight portion, etc.) of thegolf club head 3200 may be similar in many respects to the weight ports and weight portions of any of the golf club heads descried herein. Accordingly, a detailed description of the weight ports and weight portions of thegolf club 3200 is not described. Alternatively, thebody portion 3210 may not include any weight ports and/or weight portions. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In the example of
FIGS. 32-37 , theface portion 3255 may include a separate piece or an insert coupled to thebody portion 3210. Theface portion 3255 may include aface insert 3256, which may be attached to the front portion via any manufacturing methods and/or processes (e.g., a bonding process, a welding process, a brazing process, a mechanical locking method, a mechanical fastening method, any combination thereof, or other suitable types of manufacturing methods and/or processes). In one example shown inFIGS. 32 and 34 , theface insert 3256 may include twofastener holes 3258 proximate to the toe portion and heel portion of theface insert 3256. Each of the fastener holes 3258 may be configured to receive afastener 3262 for attachment of theface insert 3256 to thebody portion 3210. Thebody portion 3210 may include two fastener ports 3268 (onefastener port 3268 shown inFIG. 34 ) configured to receive thefasteners 3262. Eachfastener port 3268 may have internal threads that are configured to engage external threads on thefasteners 3262. - The
face portion 3255 may include a peripheral recessedportion 3272 configured to receive theface insert 3256. As shown by example inFIGS. 34-37 , the depth of the peripheral recessedportion 3272 may be similar to the thickness of theface insert 3256 such that when theface insert 3256 is fastened to thebody portion 3210, the face insert is positioned flush or substantially flush with theface portion 3255. Alternatively, theface insert 3256 may project from theface portion 3255. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
fasteners 3262 may have similar or different weights to balance and/or provide heel or toe weight bias for thegolf club 3200. For example, the weight of thebody portion 3210 may be increased or decreased by similarly increasing or decreasing, respectively, the weights of thefasteners 3262. In one example, the golf club head may be provided with a toe-biased weight configuration by having thefastener 3262 that is closer to thetoe portion 3230 be heavier than thefastener 3262 that is closer to theheel portion 3240. Conversely, the golf club head may be provided with a heel-biased weight configuration by having the fastener that is closer to theheel portion 3240 be heavier than thefastener 3262 that is closer to thetoe portion 3230. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - To attach the
face insert 3256 to thebody portion 3210, theface insert 3256 may be inserted in the peripheral recessedportion 3272, thereby generally aligning the fastener holes 3258 of theface insert 3256 and thefastener ports 3268 of thebody portion 3210. Thefasteners 3262 can be inserted through the fastener holes 3258 and screwed into thefastener ports 3268 to securely attach theface insert 3256 to thebody portion 3210. Theface insert 3256 may be constructed from any material such as metal, metal alloys, plastic, wood, composite materials or a combination thereof to provide a certain ball striking characteristic to thegolf club head 3200. The material from which theface insert 3256 is manufactured may affect ball speed and spin characteristics. Accordingly, theface insert 3256 may be selected to provide a certain ball speed and spin characteristics for an individual. Thus, theface insert 3256 may be interchangeable with other face inserts 3256 having different ball speed and spin characteristics. Theface insert 3256 may be coupled to thebody portion 3210 by other methods or devices, such as by bonding, welding, adhesive and/or other types of fastening devices and/or methods. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
body portion 3210 may include aninterior cavity 3282 extending between thefront portion 3250 and therear portion 3260 and between thetoe portion 3230 and theheel portion 3240. In one example as shown inFIGS. 35-37 , theinterior cavity 3282 may be defined by arecess 3284 in thefront portion 3250 that is covered by theface insert 3256. Therecess 3284 may extend from near thetoe portion 3230 to near theheel portion 3240 and from near thetop portion 3270 to the nearsole portion 3280. Alternatively, therecess 3282 may extend between thefastener ports 3268 of thebody portion 3210. In one example, therecess 3282 may be located in and/or near the regions of theface portion 3255 that generally strike a golf ball. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
interior cavity 3282 may be associated with a cavity height 3286 (HC), and thebody portion 3210 may be associated with a body height 3288 (HB). While thecavity height 3286 and thebody height 3288 may vary between the toe and heel portions, thecavity height 3286 may be at least 50% of a body height 3288 (HC>0.5*HB). For example, thecavity height 3282 may vary between 70% and 85% of thebody height 3288. With the cavity height 3285 of theinterior cavity 3280 being greater than 50% of thebody height 3288, thegolf club head 3200 may produce relatively more consistent feel, sound, and/or result when thegolf club head 3200 strikes a golf ball via theface portion 3255 than a golf club head with a cavity height of less than 50% of the body height. However, thecavity height 3286 may be less than 50% of thebody height 3288. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In one example, the
interior cavity 3282 may be unfilled (i.e., empty space). Alternatively, theinterior cavity 3282 may be partially or entirely filled with afiller material 3292 to absorb shock, isolate vibration, and/or dampen noise when theface portion 3255 strikes a golf ball. Thefiller material 3292 may be an elastic polymer or elastomer material (e.g., a viscoelastic urethane polymer material such as Sorbothane® material manufactured by Sorbothane, Inc., Kent, Ohio), a thermoplastic elastomer material (TPE), a thermoplastic polyurethane material (TPU), and/or other suitable types of materials to absorb shock, isolate vibration, and/or dampen noise. For example, at least 50% of theinterior cavity 3282 may be filled with a TPE material to absorb shock, isolate vibration, and/or dampen noise when thegolf club head 3200 strikes a golf ball via theface portion 3255. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In another example, the
filler material 3292 may be a polymer material such as an ethylene copolymer material to absorb shock, isolate vibration, and/or dampen noise when thegolf club head 3200 strikes a golf ball via theface portion 3255. In particular, at least 50% of theinterior cavity 3282 may be filled with a high density ethylene copolymer ionomer, a fatty acid modified ethylene copolymer ionomer, a highly amorphous ethylene copolymer ionomer, an ionomer of ethylene acid acrylate terpolymer, an ethylene copolymer comprising a magnesium ionomer, an injection moldable ethylene copolymer that may be used in conventional injection molding equipment to create various shapes, an ethylene copolymer that can be used in conventional extrusion equipment to create various shapes, and/or an ethylene copolymer having high compression and low resilience similar to thermoset polybutadiene rubbers. For example, the ethylene copolymer may include any of the ethylene copolymers associated with DuPont™ High-Performance Resin (HPF) family of materials (e.g., DuPont™ HPF AD1172, DuPont™ HPF AD1035,DuPont® HPF 1000 and DuPont™ HPF 2000), which are manufactured by E.I. du Pont de Nemours and Company of Wilmington, Del. The DuPont™ HPF family of ethylene copolymers are injection moldable and may be used with conventional injection molding equipment and molds, provide low compression, and provide high resilience. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
interior cavity 3282 may be partially or fully filled with thefiller material 3292. In one example, therecess 3284 may be filled with thefiller material 3292 prior to attaching theface insert 3256 to theface portion 3255. In one example, theinterior cavity 3282 may be filled with thefiller material 3292 via any one of theweight ports weight ports 3320. In one example as shown inFIG. 35 , theweight port 3324 may be connected to theinterior cavity 3282 via anopening 3294. Similarly, theweight port 3322 may be connected to theinterior cavity 3282 via an opening (not shown). Thefiller material 3292 may be injected in theinterior cavity 3282 from theweight port 3324 via theopening 3294. As thefiller material 3292 fills theinterior cavity 3282, the air inside theinterior cavity 3282 that is displaced by thefiller material 3292 may exit theinterior cavity 3282 from theweight port 3322 through the opening (not shown) that connects theweight port 3322 to theinterior cavity 3282. Accordingly, theweight port 3322 may function as an exit port for the displaced air inside theinterior cavity 3282. After theinterior cavity 3282 is partially or fully filled with thefiller material 3292, theweight ports weight portions filler material 3292 may be injected in theinterior cavity 3282 from theweight port 3322, while theweight port 3324 functions as an exit port for the displaced air inside theinterior cavity 3282. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - For example, at least 50% of the
interior cavity 3282 may be filled with thefiller material 3292 to absorb shock, isolate vibration, dampen noise, and/or provide structural support when thegolf club head 3200 strikes a golf ball via theface portion 3255. With the support of theback wall portion 3284 and filling at least a portion of theinterior cavity 3282 with thefiller material 3292, theface portion 3255 may be relatively thin without degrading the structural integrity, sound, and/or feel of thegolf club head 3200. In one example, theface portion 3255 may have a thickness of less than or equal to 0.075 inch (e.g., the thickness of the cavity wall portion 3282). In another example, theface portion 3255 may have a thickness of less than or equal to 0.060 inch. In yet another example, theface portion 3255 may have a thickness of less than or equal to 0.050 inch. Further, theface portion 3255 may have a thickness of less than or equal to 0.030 inch. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. The apparatus, methods, and articles of manufacture described herein may be implemented in a variety of examples, and the foregoing description of some of these examples does not necessarily represent a complete description of all possible examples. Instead, the description of the drawings, and the drawings themselves, disclose at least one example, and may disclosure alternative examples. - In one example, the
face portion 3255 may be in one-piece with thebody portion 3210 or be an integral part of the body portion 3210 (not shown). Thebody portion 3210 may include an interior cavity near theface portion 3255 that may be similar in many respects to theinterior cavity 3282. However, unlike theinterior cavity 3282 which may be partially defined by theface insert 3256, an interior cavity of thebody portion 3210 having a one-piece face portion 3255 may be an integral part of thebody portion 3210. The interior cavity may be partially or fully filled with afiller material 3292 via theweight ports 3322 and/or 3324 as described in detail herein. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In the example of
FIG. 38 , agolf club head 3800 may include abody portion 3810. Thebody portion 3810 may include atoe portion 3830, aheel portion 3840, afront portion 3850, arear portion 3860, atop portion 3870, and asole portion 3880. Thebody portion 3810 may be manufactured via various manufacturing methods and/or processes (e.g., a casting process, a forging process, a milling process, a cutting process, a grinding process, a welding process, a combination thereof, etc.). Thebody portion 3810 may be partially or entirely made of an aluminum-based material (e.g., a high-strength aluminum alloy or a composite aluminum alloy coated with a high-strength alloy), a magnesium-based material, a stainless steel-based material, a titanium-based material, a tungsten-based material, any combination thereof, and/or other suitable types of materials. Alternatively, thebody portion 3810 may be partially or entirely made of non-metal material (e.g., composite, plastic, etc.). Thegolf club head 3800 may be a putter-type golf club head (e.g., a blade-type putter, a mid-mallet-type putter, a mallet-type putter, etc.). Based on the type of putter as mentioned above, thebody portion 3810 may be at least 200 grams. For example, thebody portion 3810 may be in a range between 300 to 600 grams. AlthoughFIG. 38 may depict a particular type of club head, the apparatus, methods, and articles of manufacture described herein may be applicable to other types of club heads (e.g., a driver-type club head, a fairway wood-type club head, a hybrid-type club head, an iron-type golf club head, etc.). The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
body portion 3810 may include ahosel portion 3845 configured to receive a shaft (not shown) with a grip (not shown) on one end and thegolf club head 3800 on the opposite end of the shaft to form a golf club. Alternatively, thebody portion 3810 may include a bore (not shown) for receiving the shaft (not shown). The front andrear portions body portion 3810. Thefront portion 3850 may include a face portion 3855 (e.g., a strike face). Theface portion 3855 may be used to impact a golf ball (one shown as 500 inFIG. 5 ). Theface portion 3855 may be associated with a loft plane that defines the loft angle of thegolf club head 3800. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - As illustrated in
FIG. 38 , for example, thebody portion 3810 may include two or more weight regions, generally shown as afirst weight region 3912 and asecond weight region 4012. Thefirst weight region 3912 may include a firstweight platform portion 3914 having a first set of weight ports 3920 (e.g., shown asweight ports weight ports 3920 is configured to receive a weight portion of a first set of weight portions 3930 (e.g. show asweight portions second weight region 4012 may include a secondweight platform portion 4014 having a second set of weight ports 4020 (e.g., shown asweight ports weight ports 4020 is configured to receive a weight portion of a second set of weight portions 4030 (e.g. show asweight portions weight portions 3930 may be interchangeable with each weight portion of the second set ofweight portions 4030. Accordingly, each weight port of the first set ofweight ports 3920 and the second set ofweight ports 4020 may be configured to interchangeably receive any of the weight portions of the first set ofweight portions 3930 or the second set ofweight portions 4030. - The first
weight platform portion 3914 and the secondweight platform portion 4014 may have a weight platform portion length 4015 (Lwp) that may be greater than about 40% of the body portion length 3895 (LB). In one example, the weightplatform portion length 4015 may be greater than 50% of thebody portion length 3895. In one example, the weightplatform portion length 4015 may be greater than 60% of thebody portion length 3895. In one example, the weightplatform portion length 4015 may be greater than 70% of thebody portion length 3895. Accordingly, the mass of eachweight platform portion body portion length 3895. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The masses of the first and second
weight platform portions body portion 3810. The mass of each weight platform portion may be between 5% and 30% of the mass of thebody portion 3810 including the mass of the firstweight platform portion 3914 and secondweight platform portion 4014. In one example, the mass of each weight platform portion may be between about 3% and about 13% of the mass of thebody portion 3810 if the weight platform portions are made from relatively lighter metals such as metals including titanium or titanium alloys. In another example, the mass of each weight platform portion may be between about 8% and about 21% of the mass of thebody portion 3810 if the weight platform portions are made from metals including steel. In yet another example, the mass of each weight platform portion may be between about 10% and about 30% of the mass of thebody portion 3810 if the weight platform portions are made from relatively heavier metals such as metals including magnesium or magnesium alloys. Accordingly, between about 3% and about 30% of the mass of the body portion may be redistributed to thetoe portion 3830 and theheel portion 3840 by theweight platform portions body portion 3810. Further, the firstweight platform portion 3914 may be located at or proximate to the periphery of thetoe portion 3830 and the secondweight platform portion 4014 may be located at or proximate to the periphery of theheel portion 3840. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - Each weight port of the first set of
weight ports 3920 may have a first port diameter (PD1). In particular, a uniform distance of less than the first port diameter may separate any two adjacent weight ports of the first set of weight ports 3920 (e.g., (i)weight ports weight ports weight ports weight ports 3924 and 3925). In one example, the first port diameter may be about 0.25 inch and any two adjacent weight ports of thefirst set 3920 may be separated by 0.1 inch. Each weight port of the second set ofweight ports 4020 may have a second diameter (PD2). A uniform distance of less than the second port diameter may separate any two adjacent weight ports of the second set 4020 (e.g., (i)weight ports weight ports weight ports weight ports 4024 and 4025). The first and second port diameters may be equal to each other (i.e., PD1=PD2). For example, a the second port diameter may be about 0.25 inch and any two adjacent weight ports of thesecond set 4020 may be separated by 0.1 inch. The first and second port diameters may be different. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The first

weight platform portion 3914 may be attached to thebody portion 3810 with any one or more of weight portions of the first set ofweight portions 3930 or the second set ofweight portions 4030. The body portion may include a plurality of toe side threaded bores (not shown) on thetop portion 3870 at or proximate to thetoe portion 3830. When the firstweight platform portion 3914 is placed on thetop portion 3870 at or proximate to the periphery of thetoe portion 3830 as shown inFIG. 38 , the toe side threaded bores may generally align with the weight ports of the first set ofweight ports 3920. When a weight portion of the first set ofweight portions 3930 or the second set ofweight portions 4030 is inserted in a weight port of the first set ofweight ports 3920, the weight portion extends through a corresponding one of the toe side threaded bores of thebody portion 3810 such that the threads on the weight portion engage the corresponding threads in the toe side threaded bore. The weight portion can then be screwed into the corresponding toe side threaded bore to fasten the firstweight platform portion 3914 on thebody portion 3810. - The second
weight platform portion 4014 may be attached to thebody portion 3810 with any one or more of weight portions of the first set ofweight portions 3930 or the second set ofweight portions 4030. The body portion may include a plurality of heel side threaded bores (not shown) on thetop portion 3870 at or proximate to theheel portion 3840. When the secondweight platform portion 4014 is placed on thetop portion 3870 at or proximate to the periphery of theheel portion 3840 as shown inFIG. 38 , the heel side threaded bores generally align with the weight ports of the second set ofweight ports 4020. When a weight portion of the first set ofweight portions 3930 or the second set ofweight portions 4030 is inserted in a weight port of the second set ofweight ports 4020, the weight portion extends through a corresponding one of the heel side threaded bores of thebody portion 3810 such that the threads on the weight portion engage the corresponding threads in the heel side threaded bore. The weight portion can then be screwed into the corresponding heel side threaded bore to fasten the secondweight platform portion 4014 on thebody portion 3810. - Each of the weight portions of the first and second sets of
weight portions weight platform portion 3914 and the secondweight platform portion 4014 to thebody portion 3810. One or more weight portions of the first set ofweight portions 3930 and/or one or more weight portions of the second set ofweight portions 4030 may function both as weights for configuring a weight distribution of thegolf club head 3800 and as fasteners for fastening the firstweight platform portion 3914 and/or the secondweight platform portion 4014 on thebody portion 3810. Alternately, the firstweight platform portion 3914 and/or the secondweight platform portion 4014 may be fastened on the body portion by using other types of fastening mechanisms such that one or more weight portions of the first set ofweight portions 3930 and/or one or more weight portions of the second set ofweight portions 4030 may only function as weight portions. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - Each of the first and second
weight platform portions weight platform portions golf club head 3800. Each of theweight platform portions body portion 3810 and as a platform for receiving additional weights for the body portion in the form of theweight portions weight platform portion 3914 and/or 4014 may be determined to optimally affect the weight, weight distribution, center of gravity, moment of inertia characteristics, structural integrity and/or or other static and/or dynamic characteristics of thegolf club head 3800. - In one example, the
face portion 3855 may be in one-piece with thebody portion 3810 or be an integral part of the body portion 3810 (not shown). Theface portion 3855 may include a separate piece or an insert coupled to thebody portion 3810. Theface portion 3855 may include aface insert 3856, which may be attached to the front portion via any manufacturing methods and/or processes (e.g., a bonding process, a welding process, a brazing process, a mechanical locking method, a mechanical fastening method, any combination thereof, or other suitable types of manufacturing methods and/or processes). In one example shown inFIG. 38 , theface insert 3856 may include twofastener holes 3858 proximate to the toe portion and heel portion of theface insert 3856. Each of the fastener holes 3858 may be configured to receive afastener 3862 for attachment of theface insert 3856 to thebody portion 3810. Thebody portion 3810 may include two fastener ports (not shown) configured to receive thefasteners 3862. Thefasteners 3862 may be similar or substantially similar to the weight portions of the first set ofweight portions 3930 and/or the weight portions of the second set ofweight portions 4030. Accordingly, thefasteners 3862 may function both as weights for configuring a weight distribution of thegolf club head 3800 and as fasteners for fastening theface insert 3856 to theface portion 3855. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. Each fastener port may have internal threads that are configured to engage external threads on thefasteners 3862. The fastener ports of thebody portion 3810 may be similar in many respects to thefastener ports 3268 of thegolf club head 3200. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
face portion 3855 may include a peripheral recessed portion 3872 (shown inFIG. 46 ) configured to receive theface insert 3856. As shown by example inFIG. 46 , the depth of the peripheral recessedportion 3872 may be similar to the thickness of theface insert 3856 such that when theface insert 3856 is fastened to thebody portion 3810, the face insert is positioned flush or substantially flush with theface portion 3855. Alternatively, theface insert 3856 may project from theface portion 3855. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - As described, the
fasteners 3862 may be similar or substantially similar to the weight portions of the first set ofweight portions 3930 and/or the weight portions of the second set ofweight portions 4030 so that thefasteners 3862 may function to configure the weight distribution of thegolf club head 3800. Accordingly, thefasteners 3862 may have similar or different weights to balance and/or provide heel or toe weight bias for thegolf club 3800. For example, the weight of thebody portion 3810 may be increased or decreased by similarly increasing or decreasing, respectively, the weights of thefasteners 3862. In one example, the golf club head may be provided with a toe-biased weight configuration by having thefastener 3862 that is closer to thetoe portion 3830 be heavier than thefastener 3862 that is closer to theheel portion 3840. Conversely, the golf club head may be provided with a heel-biased weight configuration by having the fastener that is closer to theheel portion 3840 be heavier than thefastener 3862 that is closer to thetoe portion 3830. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - To attach the
face insert 3856 to thebody portion 3810, theface insert 3856 may be inserted in the peripheral recessedportion 3872, thereby generally aligning the fastener holes 3858 of theface insert 3856 and the fastener ports (not shown) of thebody portion 3810. Thefasteners 3862 can be inserted through the fastener holes 3858 and screwed into the fastener ports of thebody portion 3810 to securely attach theface insert 3856 to thebody portion 3810. Theface insert 3856 may be constructed from any material such as metal, metal alloys, plastic, wood, composite materials or a combination thereof to provide a certain ball striking characteristic to thegolf club head 3800. The material from which theface insert 3856 is manufactured may affect ball speed and spin characteristics. Accordingly, theface insert 3856 may be selected to provide a certain ball speed and spin characteristics for an individual. Thus, theface insert 3856 may be interchangeable with other face inserts 3856 having different ball speed and spin characteristics. Theface insert 3856 may be coupled to thebody portion 3810 by other methods or devices, such as by bonding, welding, adhesive and/or other types of fastening devices and/or methods. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
body portion 3810 may include an interior cavity 3882 (shown inFIG. 46 ) extending between thefront portion 3850 and therear portion 3860 and between thetoe portion 3830 and theheel portion 3840. Theinterior cavity 3882 may be open or accessible at theface portion 3855 and/or at thesole portion 3880. Accordingly, theinterior cavity 3882 may have afirst opening 4176 at theface portion 3855 and/or asecond opening 4178 at thesole portion 3880. Theinterior cavity 3882 allows the mass of thebody portion 3810 to be removed at or around the center portion of thebody portion 3810 so that removed mass may be redistributed to thetoe portion 3830 and theheel portion 3840 using the firstweight platform portion 3914 and the secondweight platform portion 4014 without affecting or substantially affecting the overall mass of thegolf club head 3800. - In one example as shown in
FIGS. 43 and 46 , theinterior cavity 3882 may be covered at theface portion 3855 by theface insert 3856 and at thesole portion 3880 by a cover orsole plate 4180. In one example, thesole plate 4180 may have a mass between 7% and 17% of the mass of thegolf club head 3800. In one example, the sole plate may have a mass between 10% and 15% of the mass of thegolf club head 3800. As described herein, theinterior cavity 3882 allows the mass of thebody portion 3810 to be removed at or around the center portion of thebody portion 3810. The removed mass can be also redistributed to thesole portion 3880 using thesole plate 4180 to lower the center of gravity of thegolf club head 3800 without affecting or substantially affecting the overall mass of thegolf club head 3800. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
sole plate 4180 may be attached to thesole portion 3880 with one or more fasteners. In the example ofFIG. 39 , thesole plate 4180 may be attached to thesole portion 3880 withfasteners second opening 4178 of theinterior cavity 3882 at thesole portion 3880. Each of thefasteners FIG. 46 ) in thebody portion 3810. Thefasteners weight portions 3930 and/or the weight portions of the second set ofweight portions 4030. Accordingly, thefasteners golf club head 3800 and as fasteners for fastening thesole plate 4180 to the sole portion 4080. Thefasteners golf club head 3800 by adding more mass to thesole portion 3880 without affecting or substantially affecting the overall mass of thegolf club head 3800 as described herein with respect to thesole plate 4180. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The sole plate may be partially or entirely made of an aluminum-based material (e.g., a high-strength aluminum alloy or a composite aluminum alloy coated with a high-strength alloy), a magnesium-based material, a stainless steel-based material, a titanium-based material, a tungsten-based material, any combination thereof, and/or other suitable types of materials. The physical properties and the materials of construction of the
sole plate 4180 may be determined to optimally affect the weight, weight distribution, center of gravity, moment of inertia characteristics, structural integrity and/or or other static and/or dynamic characteristics of thegolf club head 3800. - The
interior cavity 3882 may extend from near thetoe portion 3830 to near theheel portion 3840 and from near thetop portion 3870 to the nearsole portion 3880. Alternatively, the interior cavity may extend betweenfront portion 3850 and therear portion 3860 and include a portion of thebody portion 3810 between thetoe portion 3830 and near theheel portion 3840 and between thetop portion 3870 and the nearsole portion 3880. In one example, a portion of theinterior cavity 3882 may be located proximate to the regions of theface portion 3855 that generally strike a golf ball. In one example, theinterior cavity 3882 may be only atface portion 3855 similar to theinterior cavity 3282 of thegolf club head 3200. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
interior cavity 3882 proximate to theface portion 3855 may be associated with a cavity height 3886 (HC), and thebody portion 3810 proximate to theface portion 3855 may be associated with a body height 3888 (HB). While thecavity height 3886 and thebody height 3888 may vary between the toe and heel portions, the front and rear portions, and the top and sole portions, thecavity height 3886 may be at least 50% of a body height 3888 (HC>0.5*HB) proximate to theface portion 3855 or an any location of theinterior cavity 3882. For example, thecavity height 3886 may vary between 70% and 85% of thebody height 3888. With the cavity height 3885 of theinterior cavity 3882 being greater than 50% of thebody height 3888, thegolf club head 3800 may produce relatively more consistent feel, sound, and/or result when thegolf club head 3800 strikes a golf ball via theface portion 3855 than a golf club head with a cavity height of less than 50% of the body height. However, thecavity height 3886 may be less than 50% of thebody height 3888. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In one example, the
interior cavity 3882 may be unfilled (i.e., empty space). Alternatively, theinterior cavity 3882 may be partially or entirely filled with a filler material (not shown) to absorb shock, isolate vibration, and/or dampen noise when theface portion 3855 strikes a golf ball. The filler material may be an elastic polymer or elastomer material (e.g., a viscoelastic urethane polymer material such as Sorbothane® material manufactured by Sorbothane, Inc., Kent, Ohio), a thermoplastic elastomer material (TPE), a thermoplastic polyurethane material (TPU), and/or other suitable types of materials to absorb shock, isolate vibration, and/or dampen noise. For example, at least 50% of theinterior cavity 3882 may be filled with a TPE material to absorb shock, isolate vibration, and/or dampen noise when thegolf club head 3800 strikes a golf ball via theface portion 3855. In one example, the mass of the filler material (e.g., TPE, TPU, etc.) may be between 3% and 13% of the mass of thegolf club head 3800. In one example, the mass of the filler material may be between 6% and 10% of the mass of thegolf club head 3800. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - In another example, the filler material may be a polymer material such as an ethylene copolymer material to absorb shock, isolate vibration, and/or dampen noise when the
golf club head 3800 strikes a golf ball via theface portion 3855. In particular, at least 50% of theinterior cavity 3882 may be filled with a high density ethylene copolymer ionomer, a fatty acid modified ethylene copolymer ionomer, a highly amorphous ethylene copolymer ionomer, an ionomer of ethylene acid acrylate terpolymer, an ethylene copolymer comprising a magnesium ionomer, an injection moldable ethylene copolymer that may be used in conventional injection molding equipment to create various shapes, an ethylene copolymer that can be used in conventional extrusion equipment to create various shapes, and/or an ethylene copolymer having high compression and low resilience similar to thermoset polybutadiene rubbers. For example, the ethylene copolymer may include any of the ethylene copolymers associated with DuPont™ High-Performance Resin (HPF) family of materials (e.g., DuPont™ HPF AD1172, DuPont™ HPF AD1035,DuPont® HPF 1000 and DuPont™ HPF 2000), which are manufactured by E.I. du Pont de Nemours and Company of Wilmington, Del. The DuPont™ HPF family of ethylene copolymers are injection moldable and may be used with conventional injection molding equipment and molds, provide low compression, and provide high resilience. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
interior cavity 3882 may be partially or fully filled with the filler material 3892. In one example, theinterior cavity 3882 may be filled with the filler material from thefirst opening 4176 and/or thesecond opening 4178 prior to attaching theface insert 3856 and/or thesole plate 4180, respectively, to thebody portion 3810. In one example, theinterior cavity 3882 may be filled with the filler material after theface insert 3856 and thesole plate 4180 are attached to thebody portion 3810 by injecting the filler material into theinterior cavity 3882 through one or more ports (not shown) on thesole plate 4180. The filler material may be injected into theinterior cavity 3882 from one or more ports on thesole plate 4180, while the air inside theinterior cavity 3882 that is displaced by the filler material may exit theinterior cavity 3882 from one or more other ports on thesole plate 4180. - For example, at least 50% of the
interior cavity 3882 may be filled with the filler material to absorb shock, isolate vibration, dampen noise, and/or provide structural support when thegolf club head 3800 strikes a golf ball via theface portion 3855. With the filler material, theface portion 3855 may be relatively thin without degrading the structural integrity, sound, and/or feel of thegolf club head 3800. In one example, theface portion 3855 may have a thickness of less than or equal to 0.075 inch (e.g., the thickness of the cavity wall portion 3882). In another example, theface portion 3855 may have a thickness of less than or equal to 0.060 inch. In yet another example, theface portion 3855 may have a thickness of less than or equal to 0.050 inch. Further, theface portion 3855 may have a thickness of less than or equal to 0.030 inch. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. The apparatus, methods, and articles of manufacture described herein may be implemented in a variety of examples, and the foregoing description of some of these examples does not necessarily represent a complete description of all possible examples. Instead, the description of the drawings, and the drawings themselves, disclose at least one example, and may disclosure alternative examples. -
FIGS. 47 and 48 show another example of thegolf club head 3800. In the example ofFIGS. 47 and 48 , thegolf club head 3800 includes aspacer portion 4192 on thehosel portion 3845. In one example, thespacer portion 4192 may be a nut portion, a band portion, a ring portion, or a washer portion and may be at least partially ring-shaped or any other suitable shape so that thespacer portion 4192 can be positioned on, or coupled to, thehosel portion 3845. Thespacer portion 4192 may have an inner diameter that is substantially uniform or the same from a bottom portion to a top portion of thespacer portion 4192, and may be greater than the outer diameter of thehosel portion 3845. Accordingly, thespacer portion 4192 may be mounted over thehosel portion 3845 with thehosel portion 3845 extending through thespacer portion 4192 until thespacer portion 4192 is in contact with thetop portion 3870 of thebody portion 3810 as shown inFIG. 47 . The outer diameter of thespacer portion 4192 may be substantially the same or similar to the diameter of the shaft 4197 (shown inFIG. 48 ) so that when theshaft 4197 is mounted on or over thehosel portion 3845, theshaft 4197 abuts thespacer portion 4192 and thespacer portion 4192 is positioned between thebody portion 3810 and theshaft 4197. In other words, thespacer portion 4192 positions theshaft 4197 above thebody portion 3810 by a distance that is similar or substantially similar to the height of thespacer portion 4192. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - When the
shaft 4197 is inserted over thehosel portion 3845 and bent into a certain shape during manufacturing of thegolf club head 3800, the bending forces may create excessive stress concentrations at or near the connection areas between thehosel portion 3845 and thebody portion 3810. Accordingly, the connection between thebody portion 3810 and thehosel portion 3845 may fail causing thehosel portion 3845 to separate or break off from thebody portion 3810. Thespacer portion 4192 allows the stress concentrations to be moved upward from the connection region between thebody portion 3810 and thehosel portion 3845 and/or to be distributed further along thehosel portion 3845. Accordingly, thespacer portion 4192 reduces the stress concentration at or near the connection areas between thehosel portion 3845 and thebody portion 3810 to prevent failure at the connection region between thebody portion 3810 and thehosel portion 3845. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
spacer portion 4192 may be constructed from any of the materials described herein. In one example, thespacer portion 4192 may be manufactured from a rubber and/or plastic material to allow bending of thespacer 4192 with the bending of theshaft 4197 as described herein. Thespacer portion 4192 may have any height, thickness and width. In one example, thespacer portion 4192 may have a height of about 0.0625 inch (0.16 cm). In another example, the height of thespacer portion 4192 may be between 0.03125 inch (0.08 cm) and 0.125 inch (0.318 cm). The apparatus, methods, and articles of manufacture described herein are not limited in this regard. -
FIGS. 49-51 show another example of thegolf club head 3800 including an alternativeexample spacer portion 5192 for thegolf club head 3800. In one example, thespacer portion 5192 may be a nut portion, a band portion, a ring portion, or a washer portion and may be at least partially ring-shaped or any other suitable shape so that thespacer portion 5192 can be positioned on, or coupled to, thehosel portion 3845. Thespacer portion 5192 may include alower portion 5199 having aninner diameter 5197 that is substantially uniform or the same and greater than the outer diameter of thehosel portion 3845 such that thelower portion 5199 of thespacer portion 5192 can be mounted over thehosel portion 3845 with thehosel portion 3845 extending through thespacer portion 5192 until thespacer portion 5192 is in contact with thetop portion 3870 of thebody portion 3810. Thespacer portion 5192 may also include anupper portion 5193 having an inner surface orwall 5196 that curves or splays outwardly from an upper end of thelower portion 5199 in a longitudinal direction along the hosel portion 3845 (FIG. 49 ) away from the body portion 3810 (FIG. 49 ). That is, theupper portion 5193 of thespacer portion 5192 may include a surface orwall 5196 having an inner diameter that gradually increases along thesurface 5196 away from thelower portion 5199 or away from thebody portion 3810 until the inner diameter reaches its largest inner diameter 5198 (FIGS. 50-51 ). Theinner surface 5196 may be linear, non-linear, or curved, and may form a generally straight, non-curved, or curved funnel or frustoconical shape that is structured to engage matingly with a similar or substantially same shaped linear, non-linear or curved surface on thebottom portion 4198 of theinner surface 4199 of theshaft 4197, as shown inFIG. 51 . In particular, thebottom portion 4198 of theshaft 4199 can be received or inserted into anupper portion 5193 of thespacer portion 5192 such that thecurved surface 4199 of theshaft 4197 mates and engages with thecurved surface 5196 of thespacer portion 5192. Accordingly, when the shaft is received on thehosel portion 3845, thelower portion 5199 of thespacer portion 5192 is positioned or mounted between thebody portion 3810 of thegolf club head 3800 and theshaft 4197, while theupper portion 5193 of thespacer portion 5192 matingly receives or is inserted into theshaft 4199. - When the
shaft 4197 is inserted over thehosel portion 3845 into thespacer portion 5192 and bent into a certain shape during manufacturing, the bending forces may create excessive stress concentrations at or near the connection areas between thehosel portion 3845 and thebody portion 3810. Accordingly, the connection between thebody portion 3810 and thehosel portion 3845 may fail causing thehosel portion 3845 to separate or break off from thebody portion 3810. Thespacer portion 5192 allows the stress concentrations to be moved upward from the connection region between thebody portion 3810 and thehosel portion 3845 and/or to be distributed further along thehosel portion 3845. Accordingly, thespacer portion 5192 reduces the stress concentration at or near the connection areas between thehosel portion 3845 and thebody portion 3810 to prevent failure at the connection region between thebody portion 3810 and thehosel portion 3845. The increasing diameter of theinner surface 5196 of thespacer portion 5192, and the engagement of theinner surface 5192 with thesurface 4199 of theshaft 4197 provides an additional or further reduction in stress concentrations at the connection between thebody portion 3810 and thehosel portion 3845. The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - The
spacer portion 5192 may be constructed from any of the materials described herein. In one example, thespacer portion 5192 may be constructed from one or more metals or metal alloys. In one example, thespacer portion 5192 may be manufactured from a rubber and/or plastic material to allow bending of thespacer portion 5192 with the bending of theshaft 4197 as described herein. Thespacer portion 5192 may have any suitablelower portion 5199 height, total height (i.e., the height of thelower portion 5199 plus the upper portion 5193),inner diameter 5197, andinner diameter 5198. In one example, thespacer portion 5192 may have (i) a height for thelower portion 5199 of 0.03 inch (0.076 cm), (ii) an overall height (i.e., the height of thelower portion 5199 and the upper portion 5193) of about 0.1 inch (0.254 cm), (iii) aninner diameter 5197 of 0.316 inch (0.316 cm), and (iv) aninner diameter 5198 of 0.380 inch (0.965 cm). The apparatus, methods, and articles of manufacture described herein are not limited in this regard. - As the rules of golf may change from time to time (e.g., new regulations may be adopted or old rules may be eliminated or modified by golf standard organizations and/or governing bodies such as the United States Golf Association (USGA), the Royal and Ancient Golf Club of St. Andrews (R&A), etc.), golf equipment related to the apparatus, methods, and articles of manufacture described herein may be conforming or non-conforming to the rules of golf at any particular time.
